Dual Polarization and Bi-Directional Silicon-Photonic Optical Phased Array With Large Scanning Range

open access: yesIEEE Photonics Journal, 2022
We propose a large scanning range silicon optical phased array (OPA), which is polarization multiplexed and bi-directional with only one waveguide grating antenna array.

High-Q microresonators on 4H-silicon-carbide-on-insulator platform for nonlinear photonics

open access: yesLight: Science & Applications, 2021
The realization of high-quality (Q) resonators regardless of the underpinning material platforms has been a ceaseless pursuit, because the high-Q resonators provide an extreme environment for confining light to enable observations of many nonlinear ...

A 38 dB Gain, Low-Loss, Flat Array Antenna for 320–400 GHz Enabled by Silicon-on-Insulator Micromachining

open access: yesIEEE Transactions on Antennas and Propagation, 2020
Two high-gain flat array antenna designs operating in the 320–400 GHz frequency range are reported in this article. The two antennas show the measured gains of 32.8 and 38 dBi and consist of a $16\times16$ (256) element array and a $32\times32$ (1024)

Silicon-on-insulator nanophotonics [PDF]

open access: yesSPIE Proceedings, 2005
Nanophotonics promise a dramatic scale reduction compared to contemporary photonic components. This allows the integration of many functions onto a chip. Silicon-on-insulator (SOI) is an ideal material for nanophotonics. It consists of a thin layer of silicon on top of an oxide buffer.

Optimization of photoluminescence from W centers in a silicon-on-insulator. [PDF]

open access: yesOptics Express, 2019
W centers are trigonal defects generated by self-ion implantation in silicon that exhibit photoluminescence at 1.218 µm. We have shown previously that they can be used in waveguide-integrated all-silicon light-emitting diodes (LEDs). Here we optimize the

Highly-Sensitive Unbalanced MZI Gas Sensor Assisted With a Temperature-Reference Ring Resonator

open access: yesIEEE Photonics Journal, 2022
In this paper we study the gas sensing performance of a compact silicon photonics Mach-Zehnder interferometer (MZI) with a coiled sensing arm. A partially exposed sensor was fabricated using deep UV lithography, with a process resolution of 248 nm ...
